Field-free line formation in a magnetic field
WebAny current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created. Comment. WebIt is shown that magnetic intensification due to microturbulent magnetic fields may be much more efficient than that due to regular fields. The gravity center of a Zeeman line observed in circularly polarized light remains a reasonable measure of the line of sight component of the mean magnetic field for a line strength 47-1.

WebJust as field lines concentrate when entering the south pole of a magnet from a large area, an external magnetic field can be "gathered" using, for example, a cone-shaped piece of iron. The cone can be positioned such that the static field spread over a large area enters the wide end of the cone. WebExplanation. In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: . the magnetizing field H which is generated around electric currents and displacement currents, and also emanates from the poles of magnets.The SI units of H are amperes/meter.; the magnetic flux density B which acts …

WebJan 29, 2024 · The spatial information of the MNP's is encoded using a field free point (FFP), or a field free line (FFL), in which the magnetic field vanishes at a point, or on a line, respectively....
WebJul 20, 2012 · For a diatomic or linear molecule, the lowest-energy configuration is typically that of the molecular axis parallel to the magnetic field. The corresponding angular motion of the molecular axis changes from free rotation in zero field to a hindered rotation and finally pure vibrational motion in strong fields. WebThe field-free method may be expressed in terms of source functions. One first solves the field-free problem for the line source function and then substitutes it as a first …
